Flickr, the online image storage site just added a hot feature to it's service : Geotagging.

Adding location information on Flickr is done through the Organizr, under the Organize tab. Users can search for photos by location in the Explore area. Set the map to a location (world down to street level) and type in a search query. Markers will appear on the map with photos that contain that query in the tags or description of the photo.
